This catches also `ImportError`s happening in a dependency of the directly imported.
Therefore it is not best practice, this is better:

```python
import pkg_resources

try:
    pkg_resources.get_distribution('opengever.pdfconverter')
except pkg_resources.DistributionNotFound:
    INSTALLED_IMAGINGFT = False
else:
    INSTALLED_IMAGINGFT = True
```

Moving the LOGGER to __init__ would be great indeed :wink:
